Actions and potential benefits |
Potential risks or side effects |
Analgesics (general pain relieving medications, like narcotics) |
- Usually given through an IV or as an injection (shot) into a muscle. Can also be injected into the epidural space or into the spinal fluid. (See “how it’s given” under epidural block and spinal block for more information on this method of delivery).
- If given through an IV or injected into a muscle, the medication is carried in your bloodstream - so your baby gets it, too. How it affects your baby depends on how much and how close to delivery the drug is given.
|
- Can lessen pain, reduce anxiety, and help you relax during labor.
- Does not block all sensation and feeling.
- Does not cause you to lose consciousness.
- Does not slow down labor or interfere with contractions.
|
For you:
- Does not completely eliminate pain.
- May cause drowsiness or trouble concentrating.
- May decrease your memory of labor.
- May cause nausea, vomiting, or itching
- May decrease blood pressure or slow your breathing
- May give you an unwell or unhappy feeling.
For your baby (if given too close to birth):
- May cause sleepiness, which may make it harder to breastfeed (“latch on”) immediately after birth.
- May slow breathing and reflexes, and make it hard for your baby to stay warm.
|
Pudendal Block (a local anesthetic) |
- Injected into the vaginal area.
|
- Used to numb the vaginal area, usually before an episiotomy.
|
- Numbs only the vaginal area. Provides no relief from contraction pain.
- Rarely causes any negative effects on you or your baby.
|
Epidural block (a regional anesthetic) |
- A local anesthetic is used to numb an area on your lower back.
- A needle is inserted into the epidural space around your spinal canal. Then a thin catheter is threaded through it. The needle is removed and the catheter stays in place.
- You must lie or sit completely still while the needle and catheter are being inserted. This helps prevent touching a spinal nerve or vein, or piercing the spinal cord, which can cause unwanted side effects.
- It takes 10 to 20 minutes to place an epidural catheter, and another 10 to 20 minutes for the medication to take effect.
- Once the catheter is in position, you can move around, but may not be able to walk
|
- Blocks most feeling from your waist down.
- Takes 10 to 20 minutes to take effect.
- Can be used throughout labor.
- Medication can be given through the catheter more than one time, with dosage increased or decreased as needed.
- With stronger medications, can also be used for c-section.
|
For you:
- If labor doesn’t progress as expected, effects of a spinal block may wear off too soon.
- Numbness may make it more difficult to push, and may also cause loss of bladder control (temporarily requiring a catheter).
- If numbness extends to the chest, breathing may seem difficult, which may make you anxious.
- If the needle pierces the sac around the spinal cord, you may develop a bad headache, which may last several days. This is treatable.
- You may have back pain.
- Your blood pressure may drop. If this happens, you will receive IV fluids to help bring your blood pressure up.
- You may feel lightheaded, dizzy, or nauseous, or hear buzzing in your ears.
- If a nerve is touched when the epidural needle is being placed, you may feel a brief tingling sensation down one leg. Rarely, the needle may cause nerve injury.
- If medication goes into a vein, it could cause dizziness or, rarely, seizures.
- Though rare, there is risk for allergic reaction, blood clot, blood vessel injury, epidural abscess, swelling, or infection.
For your baby:
- May make your baby sleepy, which may make it harder to breastfeed immediately after birth.
- A drop in your blood pressure may cause your baby’s heart rate and breathing to slow down.
|
Spinal Block (a regional anesthetic) |
- A small needle is inserted directly into the spinal canal in your lower back.
- A small amount of medication is then injected into the spinal fluid.
- A spinal block is given only once during labor, usually just before delivery.
|
- Blocks most feeling from the chest down.
- Takes effect immediately, and lasts 1 to 2 hours.
- With stronger medications, can also be used for c-section.
|
For you:
- If labor doesn’t progress as expected, effects of a spinal block may wear off too soon.
- Numbness may make it more difficult to push, and may also cause loss of bladder control (temporarily requiring a catheter).
- If numbness extends to the chest, breathing may seem difficult, which may make you anxious.
- If the needle pierces the sac around the spinal cord, you may develop a bad headache, which may last several days. This is treatable.
- You may have back pain.
- Your blood pressure may drop. If this happens, you will receive IV fluids to help bring your blood pressure up.
- You may feel lightheaded, dizzy, or nauseous, or hear buzzing in your ears.
- If a nerve is touched when the epidural needle is being placed, you may feel a brief tingling sensation down one leg. Rarely, the needle may cause nerve injury.
- If medication goes into a vein, it could cause dizziness or, rarely, seizures.
- Though rare, there is risk for allergic reaction, blood clot, blood vessel injury, epidural abscess, swelling, or infection.
For your baby:
- May make your baby sleepy, which may make it harder to breastfeed immediately after birth.
- A drop in your blood pressure may cause your baby’s heart rate and breathing to slow down.
|
General anesthesia (Causes you to lose consciousness and blocks most sensation, including pain)
|
- The anesthesia medication is given through an IV or as an inhaled gas – or both.
- After you’re asleep, a tube may need to be inserted through your mouth into your airway to help you keep breathing.
- Note: Since food or liquid in your stomach can cause major risks, you may be told not to eat or drink once labor has started. Ice chips and small sips of water are usually okay. You may also be given an antacid to reduce stomach acid.
|
- Can be started quickly and causes rapid loss of consciousness.
- Blocks most sensation, including pain.
- Used only when absolutely necessary, such as for an emergency c-section.
|
|
Note: Though very rare, all forms of anesthesia carry risk of severe complications such as infection, bleeding, drug reactions, blood clots, paralysis, stroke, brain damage, heart attack, or death. Your healthcare providers will help you choose a form of pain relief that gives the most benefit, with the least risk, for you and your baby. |
